A common condition causing pain felt over the outer aspect of the hip sometimes radiating down outer parts of the thigh. Pain is caused by inflamed bursa over the outer part of the hip as a result of a fall or degeneration of the muscles around the hip. Sometimes pain appears without injury. Symptoms include pain when going up and down stairs or getting out of a chair and discomfort when lying on the hip at night. Treatment can include rest, anti-inflammatory medication and physiotherapy. Injection to the bursa or muscle can be helpful and as a last resort, surgery to remove the bursa and lengthen tissues to remove pressure can be considered.
